2 Use the inverse of the fraction and multiply. Use the calculator if needed. x = 117

3 To get x alone, first eliminate the number not attached to the letter. – 3 – 3 – 11 Use the inverse of the fraction and multiply. X = – 44

4 Combine Like Terms – 10x = 50 – 10 –10 x = – 5

5 To get x alone, first eliminate the number not attached to the letter x = 33 3 x = 11

6 Combine Like Terms 8x – 7 = 128 To get x alone, first eliminate the number not attached to the letter x = x = x =

7 Combine Like Terms – 1x x + 18 = 4 Move the variable term to the left. + 1x 2x + 18 = 4 – 18 –18 2x = – 14 2 x = – 7

8 Move the variable to the left. – 3x – 7 = 58 Is that true? NO! NO SOLUTION

9 Subtract 12 on both sides. – 12 – 21 Use the inverse of the fraction and multiply. x = – 105

10 To get x alone, first eliminate the number not attached to the letter –3x = – 15 – 3 x = 5

11 Distributive Property = 68 – 6x – 4x + 42 Move the variable to the left. + 6x 2x + 42 = 68 – 42 2x = 26 2 x = 13

12 Distribute the minus sign. – 4x – 7 3x = – x – 11 2 C L TC L T – 1x – 7 = – 9 – x To move the variable to the left, add x on both sides. + x – 7 = – 9 Is that true? NO! NO SOLUTION

13 C L TC L T 5x + 3 = – 2 + 2x To move the variable to the left, subtract 2x on both sides. – 2x 3x + 3 = – 2 – 3 – 3 3x = – x = – ─ 5353

14 Distributive Property 3x + 3 – 5x = 18 – 5x CLT – 2x + 3 = 18 – 5x Add 5x on both sides. + 5x 3x + 3 = 18 – 3 3x = x = 5

15 Add 7x to both sides. + 7x 2x + 14 = 32 – 14 – 14 2x = 18 2 x = 9

16 Subtract 9 on both sides. – 9 5 Multiply both sides by x = 10

17 Distributive Property 7x + 28 = 70 Subtract 28 from both sides. – 28 7x = x = 6

18 Subtract 9 on both sides. – 9 x = – 17

19 Subtract 3x from both sides. – 3x 18x + 7 = 17 – 7 18x = x = 5959

20 To get x alone, first eliminate the number not attached to the letter. – 11 2x = x = 19

21 CLT 5x + 50 = Distributive Property 5x + 50 Subtract 5x on both sides. – 5x 50 = 50 Is that true? YES! ALL REAL NUMBERS

22 You would never plan to fail… so why would you fail to plan? STUDY! STUDY! STUDY! STUDY! STUDY! STUDY! STUDY! STUDY! STUDY! STUDY! STUDY! STUDY! STUDY! STUDY! STUDY! STUDY! STUDY! STUDY! STUDY! STUDY!
